Answer:
1. B
2. C
Explanation: The law that the properties of the elements are periodic functions of their atomic numbers. And the second one is, most of the air we breathe is made of oxygen.
Answer: Molecular geometry shape of SO2 is V-Shaped or Bent (trigonal planner) , CCl4 is tetrahedral and BCl3 is trigonal planar.
Explanation:
The Lewis structures of the compounds are in the figure below.
Answer:
Mass does not change based on gravity
Explanation:
Mass is how much matter is in an object. That's why we have the same mass on Moon, Neptune, etc.
But weight depends on gravity. That's why our weight on the moon is less than Earth because the Moon's gravity is less than Earth.
Answer:
Electromagnetic radiation is made when an atom absorbs energy. The absorbed energy causes one or more electrons to change their locale within the atom.
When the electron returns to its original position, an electromagnetic wave is produced. ... These electrons in these atoms are then in a high energy state.
what does radiation do?
The main effect radiation has on matter is its ability to ionize atoms to become ions, a phenomenon known as ionization, which is very similar to the photoelectric effect. Radioactive particles or electromagnetic waves with sufficient energy collide with electrons on the atom to knock electrons off the atom
